Select diamonds in the Sophia Fiori collection are color enhanced diamonds. Sophia
Fiori uses a modern technique known as High Pressure High Heat (HPHT) which mimics
the natural forces below the earth's surface and enhances the natural inherit color
in the diamond. Sophia Fiori's color enhanced blue, yellow and green diamonds are
beautified through this process, which is permanent, irreversible and cannot be
detected by the human eye even under magnification.
